Returns true if
- domain is an ip address and host is the same ip address
- domain is a domain and host is the same domain
- domain is a domain and host is a subdomain of it
Does not do any normalization. Probably a good idea to call
`host_matches_domain(
urlcanon.normalize_host(host), urlcanon.normalize_host(domain))`.
